On-site measurement, adjustment and balancing of commercial HVAC systems for new installations, upgrades and compliance programs, delivered with verified reporting.
.avif)
We deliver testing, adjusting and balancing (TAB) services across a range of commercial HVAC systems.
On-site measurement and adjustment of supply, return and exhaust airflows to ensure each space receives the airflow it was designed to receive.
Measurement and adjustment of chilled water and condenser water flow rates to confirm correct distribution across plant and terminal equipment.
Verification of outside air volumes and exhaust rates to confirm ventilation performance meets occupancy and regulatory obligations.
On-site testing to confirm temperatures, pressures, controls and airflow perform correctly against design intent.
Structured TAB reports documenting measured performance data, issued at completion to support handover and compliance audits.





We test, adjust and balance commercial HVAC systems across new builds, refurbishments and existing buildings throughout SEQ. From airflow balancing to ventilation verification and certified reporting, works are delivered under qualified supervision with full documentation.


Mechanical services built for operational reliability and long-term performance.






Trusted by tradespeople across South East Queensland for a reliable, professional and rewarding place to work.
“We had a fantastic experience working with Mark and the team at Chill Merchants.
They installed a large air con system in our workshop and office where several high temp machines run all day. These ducted units are big and heavy, and I wanted experienced tradesmen doing the job, and that's what we got.”

“Chill Merchants were engaged by Bryant Building Contractors to deliver the mechanical services package at Bryant’s recently completed, Energy Queensland Esitrain Redevelopment project and performed strongly from pre-tender until completion.
Their team completed all contracted works competently, efficiently, and in full accordance with project drawings and specifications. Communication was clear, site coordination was smooth, and their commitment to meeting program deadlines was evident throughout the build. Chill Merchants' professionalism and reliability contributed to a seamless delivery, and Bryant will actively seek their services for future projects.”

Common questions about working with Chill Merchants across Brisbane and South East Queensland.
Commissioning is where an HVAC system proves whether it actually works the way it was designed to.
After installation, the system must be tested, adjusted, balanced, and fine-tuned so airflow, water flow, temperatures, and controls operate as intended. Without proper commissioning, systems can run, but not perform.
Most recurring comfort complaints, uneven temperatures, and excessive runtime issues trace back to poor commissioning. It’s the difference between a system that technically turns on and one that delivers stable, reliable comfort.
Testing, Adjusting and Balancing (TAB) forms a core part of the commissioning process. It verifies that the installed system matches the design intent and performs correctly in real-world conditions.
Air balancing is what ensures each space receives the airflow it was designed to get.
If airflow is not correctly adjusted, one room may be over-supplied while another struggles for fresh air. That leads to hot spots, cold spots, odour complaints, and ongoing call-backs.
Ventilation compliance also relies on correct balancing. Outside air volumes and exhaust rates must be verified to ensure indoor air quality is maintained. These requirements are governed by Australian Standards such as AS 1668, but standards alone don’t guarantee performance, commissioning does.
A ventilation system only works properly when it is measured, adjusted, and verified on site.
Commissioning directly impacts comfort, stability, and operating costs.
If airflow is too high in some areas and too low in others, temperature control becomes unstable. The system then works harder to compensate, increasing energy consumption and wear on equipment.
Proper commissioning ensures diffusers, dampers, control setpoints, and system sequencing are tuned to suit the building’s actual conditions. When done correctly, the system operates more efficiently, maintains stable temperatures, and reduces unnecessary runtime.
Many comfort issues are not equipment failures, they are commissioning issues.
Yes. Commissioning should be considered mandatory for any new installation or major upgrade.
When plant is replaced, ductwork modified, ventilation rates adjusted, or controls reconfigured, system performance changes. Commissioning verifies that those changes have not created pressure imbalances, ventilation deficiencies, or control conflicts.
It also provides documented performance data for handover, giving building owners and facilities managers confidence that the system is operating correctly.
Installation is only half the job, commissioning completes it.
The mechanical contractor delivering the project is responsible for ensuring the system performs as designed.
Commissioning may involve internal TAB processes or coordination with specialist balancing contractors depending on project scale. Regardless of project size, performance verification is a core responsibility.
Chill Merchants ensures systems are commissioned under qualified supervision so airflow, ventilation, controls, and system performance align with design intent, NCC requirements, and relevant Australian Standards.
